mechanism which may be used for railway for railway cross purposes, and particularly ings Where there is danger and where a moving as well as a sounding device is needed to attract the attention of the eyes as well as of the ears'of people in the neighborhood of the signal.

It is also an object of the invention to provide a signaling device in which a rocking target may be oscillated by means of a suitable motor preferably of the electric' type, the structure being such that-the motor may be removed fromposition and another set into its' place for operating the target while the disabled motor is repaired.

It is also an object of the invention to provide a signaling device in which a rock shaft is actuated by suitable mechanism, the rock shaft operating a target and being also provided with an actuating member adapt ed to operate a gong mechanism at each os-' cillation of the target.

In the accompanying drawings, forming part of this specification,

Figure 1 1s a vertical, sectional view taken through the casing of a signaling device" constructed in accordance with the present invention, the section being taken to one side of the mechanism in said casing.

will now be more specifically described, rei-.

erence being had to the drawing, in which 5 indicates a casing or box adapted to contain the actuating mechanism of the signaling device, the said box being so constructed that it may be readily mounted upon a post, arm or other desired support in any suitable manner. lVithin the casing 5 is, jour- .naled a rock shaft 6 mounted in suitable bearings l carried by the base of the casing 5. The said rock shaft is preferably hollow, and may be made of ordinary piping, the ends thereof being allowed to project through openings in the sides of the casing 5. One end of. the rock shaft is con nected by a T-coupling 8, with an upwardly extending hollow-arm 9 which can ries a target 10 at its upper end. The said arm 9 may also be made of ordinary piping screwed at its lower end into the coupling 9 is preferably slotted for a suilicicnt distance to r ceivethe lower edge of the target 10. The flange of the target is inserted in said slot as shown in Figs. 1 and r, and rivets o1 either one of the lenses may be readily removed at any time for gaining access to the lamp or for cleaning the lenses. The lamp 14L is preferably auclectric lamp and conductorslll and 20 pass through the hollow arm 9 to supply the said lamp with a The lower end of the 'l"-coupling 8 also carries a lamp as 21, and the end of the rock shaft 6 upon the other side of the casing 5. is usually pro- \"l'IlHl with a lamp 522, an elbow 23 being pro- Vl(l(?(l upon the and of the shaft to hold said lump. llhc (.-oi1(luctoi's cxtend through the hollow arm 9, the hollow shaft 6 :mil the hollow coupling 8. as well. as the elbow so to connect all of the said lamps in series. The conductors 19 and 20 are led from the hollow shaft ii through an openfl-l mrrncd. therein, and thence to my suitable source of clcixi-icnl cnei-i'gy.

The shaft 6 pi'cfcmbly oscillated at a moderate s}; ml. to throw the target 10 back and forth, thus attracting the cycs of all pusscrs. Tho oscillation is n'cfcrahly no voinplishml through the agency of suitable gearing and interconnecting :ucunsthogearing being adapted. to receive its actuation from. a pinion secured. to the shaft of an electric motor 26. The electric motor is rcinovably n'iounteclupon a boss 27 formed on the plate of'thc casing 5, so that the said motor can be readily set in place or removed for repair when required and another motor may be substituted therefor; without interfering with the othci' mechanism of the device The pinion Il'lBSl'lQS with u gear Wheel 28 which is carried by it sha ft 29 joui'naled upon standards and 31 Within the cus ing The Stl l gear 28 comics a pinion 32 upon onc 0i .liiccs which. meshes with :1 gear Wheel secured to {L countershai't 3-- ax'm-nged adjacent to the shaft The said countershalt 34 jcui-i'uilcd upon standar is 35 and 36 in the casing 5i and one end of soisl shaft 3 is provided with a crank arm 3'? which connected by means of it link 38 with on 1 "in 40 secured. to the rock shaft 6. Thou (l mud-e loiwoithnn thccrim-k arm 37 so that the said arm ill will only be oscillated though the (i-uni: au'm turns ontii'cly about its axis. It will he tcudily understood that when the motor 215; is HQ" tuutcd that its pinion will drive the train of gearing just described and cause the oscillation of tho ii, incl the ill3"i7 arm 9 Well, is the motor is kopt rum The souiniing' in" gong,'n'icchanisni cmloyal is opcm'tccl in couj inct. n with the arge?) anti to accomplish this purpose, is ictor 4-1. is rigidly sccurctl to ho shaft 6 and pizo'violecl new: out pci 'pheit-y with the tc'th =9 in. with. tho teeth of in i2." n- 2 oil to u, vciticzii shaft vertical sh; mounted at its h tuppci" sun 25 o g i 4.1.

shaft 44. It will'bc readily understood that as the sector 41 is oscillated b the rocking of the shaft 6, that the sha. t lsi will be turned back and forth so that the gong or boll will be struck: by the topper at each extreme of its movement.

It will be. understood that the mounting of the various shafts in the mechanism may be al'tcretl'in dicta-ii Without departing from the spirit of the invention. The provision of tho rock shaft with a target carrying arm and ii gong operating arm or sector makes it possible to always secure both a sight and sound signal, and the i'imnncr of mounting the actuating motor so to rock said shaft (3 is important since the motor can be so z'ceulily rcinovcil for repair and replaced by another (luring the time irequirecl for such repair. Tho gong opersting mcchonisin is so constructed that a positive sounding of tho gong is secured ovary time the target is swung in either direction.

The construction of the target cozwying arm 9 is also important since 2, very strong mounting of the target is sccurcd, yet with a simple and easily constructed arrangement of the parts. The lamp in the target can also be recchco. with-out discozmeoting any of the ports of the tot-get device, or without taking the target from the said. mm 9. It will he readily understood that the abovc macho nlsm may ho sot at any point of dangle! or at railway crossings, and. its mot-0r he so Y connected. with track opcirating mos-no that the signal may be set in operation upon tho approach of it car or tram, and. caused to stop again after the point of danger has been passed. by tho said cm or train.
